Input Terminal for PID Feedback

Factory Setting: 00

Settings

00: No function

01: Input via AVI

02: Input via ACI1

03: Input via ACI2

04: Input via External Reference

 This parameter is to set the source of PID control feedback signal. The source could be AVI, ACI1,

ACI2 or external reference that defined by 04-24.

 When this parameter is set to 00, PID feedback control function is disabled.

 When this parameter is set to 02/03 and analog input current of ACI1/ACI2 is lower than

Pr.04-13/Pr.04-17, EF warning will pup-up.

 If this parameter isn’t set to 00, AC drive will automatically start-up PID feedback control. Output

frequency is calculated by master frequency and PID feedback signal.

PID Control Detection Signal Reference

Factory Setting: 1000.0

Settings 0.0-6550.0 Unit: 0.1

 Please refer to 04-09 to 04-20 if this parameter is set to PID feedback control.

PID Feedback Control Method

Factory Setting: 00

Settings

00: Negative feedback control

01: Positive feedback control

 This parameter could set the calculation method of deviation signal during PID feedback control

circuit.

 When this parameter is set to 00: when negative feedback control, the deviation equation is deviation

= target value – detection signal. When increasing output frequency will increase detection value,

this setting should be chose.
